10 #
11 # Originally the Go build system used it as a smoke test to quickly
12 # flag portability issues in builders named "misc-compile" or "all-compile".
13 # As of CL 464955, the build system uses make.bash -compile-only instead,
14 # so this script no longer runs in any automated fashion.

16 # Options:
17 # -e: stop at first failure
